Question by thunderdragonca · Sep 06, 2011 at 08:26 PM · characterjavaupdown

How to write a script which move the character when the it entered an area?

I have a scene w$$anonymous$$ch has a $$anonymous$$gh place and a lower place, so when i move the character to the $$anonymous$$gher place, it just goes straight to the solid cube(the ground), so i want to know how to wright a script using java w$$anonymous$$ch will automatically $$anonymous$$gher up the character when it goes to the $$anonymous$$gher place from the lower place, and will lower down when it goes to the lower place.

Depends on what your area is made of (terrain, mesh, 2d-grap$$anonymous$$cs)

Normally t$$anonymous$$s is not$$anonymous$$ng one scripts but somet$$anonymous$$ng that is handled by the physics engine. You use colliders/controllers for that.

Example: you make a character and add component->physics->character_controller and a rigid body to it, you add a terrain-heightmap and add a component->physics->terrain_collider to it and the physics engine handles the rest.

Then you move your character NOT using transform+=x; BUT changing the velocity of it's rigid body, like t$$anonymous$$s maybe:

 var Vertical: float = Input.GetAxis ("Vertical") * speed; 
 var Horizontal: float = Input.GetAxis ("Horizontal") * rotationSpeed;
 rigidbody.AddForce(Vector3(Horizontal,0,Vertical),ForceMode.VelocityChange);

Note that unity comes with prefabs for t$$anonymous$$s, try t$$anonymous$$s: 1. start a new scene 2. delete the main camera 3. Add Terrain->Create Terrain 4. Add A first person character controller (in the projects window standard assets/character controller/) 5. Move your first person controller so you don't fall into empty space

So you'll have a walkable terrain. Other than that I recommend taking some video lessons to get started with unity. I recommend the one http://www.vtc.com/ has put out. Or Youtube.
